Since NS was talking about blingy watches...here is my bling shot of the week. Its a 1994 16528 Daytona in YG with cal 4030 (which used an El Primero as a base movement). It's blingy so I don't wear it often, but it was my Dad's and I really like it. It doesn't look quite so blingy when its not in bright light, and interestingly as gold can oxidize over time (this one has...it has taken on a slightly rosier hue).
Going back a day or so to quote this, and let everybody have a second look...but I'm intrigued by Dino's observation about yellow gold oxidizing into something a bit more rosy.
Rose gold seems far more popular these days, although I consider myself more of a yellow gold person.
I'm kind of old school maybe, and my wedding band is yellow, but-- and this might make me sound like a bitch -- I also don't feel like the rose gold tones complement my skin / complexion / hair color, etc.
Having said that, it would be pretty awesome to have a piece (not necessarily the always-cool Daytona), but any watch that sort of takes on that kind of aging process in the metal.
If it started yellow, I'm sure it's not going to turn out like "Everose" (in Rolex-speak, a different alloy anyway) but a little bit of a maturation, a little patina that you've earned along the journey......always trés cool.
